Abstract
A wireless device may compute transmission power of an uplink packet employing a first parameter calculated by accumulation of an initial value and at least one power control value corresponding to a sequence of subframes. The sequence of subframes starts from an initial subframe and ends with the first subframe. The initial subframe is identified by the most recent subframe before the first subframe with one of the following events: a predefined transmit power parameter value is updated by higher layers; and a random access response is received corresponding to a transmitted random access preamble on a secondary cell.
